CATERERS'VEHICLE.

SPECIFICATION forming part of Letters Patent No.'464,058, dated December1, 1891.

Application filed June 21, 1888. Serial 110.377.744. (No model.) v ncompanying drawings, is aspecification, like letters on the drawingslrepresenting like parts.

This invention relates to caterers Wagonsor vehicles for thetransportation of foodfrom creams, &c.

one point,'as a supply-station or cookery, to another or distant point,as the house of the consumer, it being an improvement upon the caterersWagon shown and described in my United States Patent No. 377,594, dated'February 7, 1888.

This invention has for its objectto provide a wagon or vehicle by whichthe food placed hot or substantially hot in the vehicle or a compartmentthereof may be delivered to the consumer in the same or substantiallythe same condition, While other articles of food placed coldin the saidvehicle may be maintained coldespecial1y in warm weather.

In accordance with my invention the body of the wagon is renderednon-heatv conductsium carbonate, orother non-heat-conducting substance,preferably interposed between an inner and outer wall of the said wagon.

The interior'of the wagon may and-preferably will be divided into two ormore sepay rate or independent compartmentsfor the reception ofdifferent articles of food"'that is, one compartment may be used toreceive'articles which f it is desired to maintain hot, such as roasts,&c., while another compartment receives articles to be maintained cold',such 'as The particular features of my invention will be pointed out inthe claim at the end o this specification.

Figure 1 is a longitudinal ,',vertical section` of a caterers wagonembodying my invention; Fig. 2, aI transverse section of the wagon,shown in Fig. lon line looking toward the right; Fig. 3, a detail to bereferred tog and Fig. 4 is a transverse section through the body of thewagon, shown in Fig. 1 on line y y, the cans or receptacles being shownin elevation.

Thewagon or vehicle A, mounted upon forward wheels a and rear wheels a',has its body portion supported, as shown, upon the crankaxle a2 of thesaid rear wheels.

` The body portion of the wagon or vehicle, herein shown as oblongorbox-shaped, is preferably composed of an outer wall a3 and an linnerwall a4, preferably of metal, the said walls havingi-nterposed betweenthem alayer a'of asbestus, carbonate of magnesio., or otherusu'al orwell-known non-heat-conducting substance, by means of which heat withinthe said body'port-ion is prevented from radiating outward,'while theheat outsideof the said body portion is prevented from penetrating Yintothe interior thereof. f

The body portion is herein shown as divided into'two compartments b bbya double wall b2 and layer a5 of non-heat-conducting material interposedbetween said double Wall,the said compartments being respectivelyaccessible from Without by means of doors b3 b4, also composed, asshown, of a double wall and an interposed layer of non-heat-conductingmaterial. The compartment b may and preferably will be dividedhorizontally by a reticulated plate or frame b5, supported uponybrackets b on the walls 01.4 b4 and other brackets b, (shown asangle-irons,). secured to the sidewalls bloot the compartment b, thevsaid side Walls being herein shown as composed of metal platesyseparated from th'e inner walls .a4 of the body to` leave a chamber orair-passage bz, which communicates with'the chamber b `by one ormore'openings bw, which may be covered by registers cs. (Shown only inFig; 1.)

' The body 'of the wagon near its bottom is provided with one orI moreopenings b, (see Fig. 4,) which constitute outlets for the chamber b.

The compartment b has placed in it a numlber of preferably metallicrcans or receptacles b5, in which the food-sucli as roasts, &c.-to bemaintained'h'o't or substantially hot is placed, thc lowerrnost of saidcans or receptacles being supported, as shown, by the reticulated plateb5, and the upper cans or receptacles, as shown, by shelves b", havingtheir ends supported by Ythe brackets bm. The compartment b is providedin a similar manner with a series of shelves c, supported 'I ce uponbrackets c', secured to the Walls of the said compartment, the saidshelves supporting cans or receptacles ci, containing food to bemaintained cold--snch, for instance` as ices, creams, dsc.

The compartment l) is heated to the desired or required degree tomaintain thc food in the cans h hot or substantially hot by a heater,herein -shown as vapor-fuel burners c, connected, asvby pipe 0*, to asuitable supply-tank c", preferably located outside ot' the wagon, thesupply of fuel, which may be naphtha, being controlled by a Suitablecock or valve c, the burner-pipe c being capable of being turned, as ona Swivel, in usnalorwollknown manner.

The humidity of the air within the compartmentb is maintained, as hereinshown, by providing a dish or receptacle c2, containing water, or it maybe by means of steam, as ini my patent referred to.

`Air to `support combustion and to effect a:

ventilation to carry ofl any obnoxious odors may be admitted throughsuitable openings or vent-passagesc7 in the bottom of the wagon, thesaid air passing from the compartment l through suitable ventilators cBinto the chamber bl2 and from said chamber out through the outlets b,

In the winter or colder season the air in the compartment b issufficiently cold to maintain the food in the cans c2 cold or in propercondition; but in summer or warmer weather the temperature of thecompartment U' may be kept low by means of ice placed in a receiver'orbox e, attached to or forming part of the said compartment.

The air iu the compartment b', rendered cold bythe ice in the receivere, is circulated through said compartment by means of afan or blower d,of usual or well-known construetion, having its shaft d extended throughthe wall of the body portion of the wagon and provided with a pulley di,connected by a belt fl `to a pulley d on the hub ofL the wheel a', theinner end ot` the shaft d' being supported in an upright d", secured toa reticulated plate d, forming` the bottom of the said compartment, thefan or blower heilig operated by the rotation of the wheels a.

I have herein shown and described the body of the vehicle as mountedupon wheels; but it is evident that in the winter-time the said body maybe mounted upon runners, and by the term whecls, as hereinafter employedin the claim, I wish to be understood as including runners.

I claimi 'lhe caterer-s vehicle herein described, comprising the bodyconstructed with double external walls lined with a non-conductor oiheat, the partition-wall b2, similarly coustructed and dividing the bodyinto two coinpletely-isolated compartments, one of said con'ipartmentsbeing a heat-iiig-compartment and the other a refrigerating-compartmentand supplied with the proper apparatus for these purposes, supplementalwalls b1 in said beating-compartnient forming Vertical chambers openinginto the heati11g-compartment at one end and to the external atmosphereat their other ends to ventilato said comparte ment, land independentdoors for the two compartments, substantially as described.

ln testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH F. liALDWIN.
